Single operator exchange biliary catheter
First Claim
1. In a catheter for use in biliary procedures including a shaft having a proximal end and a distal end, the improvement comprising:
- a guidewire lumen carried by the shaft extending from a location proximal the distal end of the shaft to a location proximate the distal end of the shaft; and
means for accessing the guidewire lumen from a location exterior to the catheter shaft, located distal the proximal end of the shaft said means including a first opening through the wall of the catheter shaft into the guidewire lumen located proximal the distal end of the shaft, a second opening through the wall of the shaft located proximal the first opening and a channel which gives access to the guide wire lumen extending longitudinally between the first opening and the second opening.

Abstract
Catheter for use in biliary procedures, including a shaft having a proximal end and a distal end. A guidewire lumen is carried by the shaft extending from a location proximal the distal end of the shaft to a location proximate the distal end of the shaft. An opening is included for accessing the guidewire lumen from a location exterior the catheter shaft located distal the proximal end of the shaft. The guidewire lumen may be formed integral the catheter shaft. The catheter may be used in rapid exchange catheter procedures. The catheter may further include a port and channel design including a first opening into the guidewire lumen located proximal the distal end of the shaft, a second opening located proximal the first opening, and a channel extending longitudinally between the first opening and the second opening.

5. A method of positioning a biliary catheter including a shaft having a proximal end and a distal end, within a patient'"'"'s alimentary canal comprising the steps of:
-
providing a guidewire lumen within the catheter, extending from a location proximal the distal end of the shaft to a location proximate the distal end of the shaft; providing a port through a sidewall of the shaft into the guidewire lumen, the port located distal of the proximal end of the shaft; and moving a guidewire through the port, relative to the shaft. - View Dependent Claims (6)

7. A method of exchanging a catheter during a biliary endoscopic procedure comprising the steps of:
-
passing an endoscope having a lumen extending longitudinally therethrough, through a patient'"'"'s mouth into the alimentary canal; positioning a distal end of the endoscope proximate the opening into the biliary tree; passing a guidewire through the lumen of the endoscope; providing a catheter having a guidewire lumen carried by the shaft extending from a location proximal a distal end of the shaft to a location proximate the distal end of the shaft, including a first opening into the guidewire lumen located distal the proximal end of the shaft; and advancing the catheter over the guidewire, wherein a proximal end of the guidewire exits the first opening. - View Dependent Claims (8, 9, 10)
